AI Analysis

●●SolidBig BrainNiche Gem

Counter AI code dependency by building framework internals yourself — timely motivation.

Strengths
  • •Addresses real problem: developers losing understanding when AI writes their code.
  • •Follow-along build approach creates deeper mental models than reading documentation.
Weaknesses
  • •Only 2 lessons published — too early to judge full series quality.
  • •Build-your-own-framework tutorials already exist for FastAPI and Starlette.

Post Description

I am writing a series of lessons on building an ASGI framework from scratch. The goal is to develop a deeper understand of how frameworks like FastAPI and Starlette work.

A strong motivation for doing this is because - I have been using AI to write code lately. I prompt, I get code, it works. But somewhere along the way I see engineers stop caring about what is actually happening.

So, this is an attempt to enable the community to think beyond prompts and build deeper mental models of things we use in our day to day lives. I am not sure about the usefulness of this but I believe there are good lessons to be learnt doing this.

The series works more as a follow along where each lesson builds on the previous one. By the end, you will have built something similar to Starlette - and actually understand how it works.
